Title (EN) FULLY AUTOMATED CALIBRATION FOR ACOUSTIC PYROMETRY
(FR) ÉTALONNAGE PLEINEMENT AUTOMATISÉ POUR PYROMÉTRIE ACOUSTIQUE
Abstract:
(EN) A method of calibrating transceiver positions inside an acoustic pyrometry measuring vessel that contains a plurality of transceivers, includes determining (40) a speed of sound in the acoustic pyrometry measuring vessel from a temperature and gas composition of a gas inside the acoustic pyrometry measuring vessel, acquiring (41) time-of- flight (TOFs) Atij measurements from a plurality of pairs ij of transceivers inside the acoustic pyrometry measuring vessel, estimating (42) a radius of the acoustic pyrometry measuring vessel from an average of the acquired TOF measurements, and using (43) an estimated radius of the acoustic pyrometry measuring vessel to estimate errors A0j of displacement angles of the transceivers.
(FR) L'invention concerne un procédé d'étalonnage de positions d'émetteur-récepteur à l'intérieur d'une cuve de mesure de pyrométrie acoustique qui contient une pluralité d'émetteurs-récepteurs, la procédé incluant la détermination (40) d'une vitesse du son dans la cuve de mesure de pyrométrie acoustique à partir d'une température et d'une composition d'un gaz à l'intérieur de la cuve de mesure de pyrométrie acoustique, l'acquisition (41) de mesures Atij de temps de vol (TOF) à partir d'une pluralité de paires ij d'émetteurs-récepteurs à l'intérieur de la cuve de mesure de pyrométrie acoustique, l'estimation (42) d'un rayon de la cuve de mesure de pyrométrie acoustique à partir d'une moyenne des mesures TOF acquises, et l'utilisation (43) d'un rayon estimé de la cuve de mesure de pyrométrie acoustique pour estimer des erreurs A0j d'angles de déplacement des émetteurs-récepteurs.
